First Auto attempt. First time using LED

Ok I'm a old school grower . Used to grow tripples with HID lights. Always fascinated with the idea of LED. So I purchased a very cheap red/ blue led , apparently 300 watts. Ya right . It pulls 45 watts from the wall. So I added a Walmart yes a Walmart 25 watt COB light. Space is 18 by 20 inches. Dirt is a Rona pro mix with slow release fertilizer , benneficial fungi , 40 percent organic compost . I'm using a tiny amount of water soluble chemical fertilizer to feed the fungi to get it active . Then I top dress with same dirt every two weeks. I'm using a one gallon pot to reduce size .
